2017-03-24Move feature depth calculation to Feature class.Martin Miller
And also fixed F computation for features. I realized that the features were transformed from image to body frame prior to being passed to State. This makes sense because the State really doesn't need to know about Camera objects. Since the camera was no longer necessary inside of State it made sense to move the depth computation from Camera::ref2body() into a method in the Feature class that does not rely on camera parameters. Additionally, the depth solver was changed from a simple matrix inversion to a least squares calculation. Fx in the feature class was fixed to take into account dt. Updating Pkk1 is in the process of being modified to handle features.

2017-03-18Major rewrite moves state variables into state.Martin Miller
Rather than maintain X and P in the main function they are moved into the body and state classes, respectively. This will become much more important when features are added and the accounting becomes more complicated.

The State class contains the body and feature classes. It is responsible for composing matrices, and performing Kalman updates.
